Insert entity

[zchoi]

I have just started contacting dxf files, can we read out the coordinates of the entity in the insert, for example,some lines' startpoint and endpoint?

There is no specific functionality for that, but all the necessary tools are there. To get the entities of a block in world coordinates they need to be transformed by the transformation matrix of the insert, take a look at the Insert's method Explode().
